Title: Drive force transmission mechanism for pair roller
Inventor: KAWAKUBO KAZUO
IPC: F16C13/00
Filed: 1979-04-24
Abstract: PURPOSE: To make the peripheral speeds of pair rollers in a thermal fixing device for a duplicator or the like by permitting drive force to be transmitted to the pair rollers in accordance with the changes of the outer diameter thereof.  
     CONSTITUTION: A drive gear 4 is rotated by a drive motor 3, and the drive force is transmitted through a uni-directional clutch 6 integrally coupled to the gear 5 to a roller 1 for driving the roller. A pressure application roller 2 is held in forced contact with the outer periphery of the roller 1 and rotated by the frictional forces. The gear 5 is in mesh with a gear 7, and the drive force is transmitted through a uni-directional clutch 8 integrally coupled to the gear 7 to the roller 2 for driving the roller. When the outer diameter of both the rollers is greatly changed due to heat or other causes, a slip is produced in the uni-directional clutch, so that both the rollers are rotated at an equal peripheral speed with the roller 1 being driven.

Title: Automobile collision prevention radar
Inventor: SEKINE CHOGO
IPC: G01S13/93
Filed: 1991-03-15
Abstract: PURPOSE:To prevent the interference with the other automobile-mounted same device, simultaneously measure a distance and speed and realize a high-detection performance, high reliable and inexpensive device by small power. CONSTITUTION:Spectrum scattering is applied. A PN(pseudo noise) code train is produced as a first PN code train and a second PN code train. An epoch EP1 of the first PN code train is made the chips CH 2 of the second PN code train and the epoch EP2 of the second PN code train is taken sufficiently longer than the going and returning time of an electric wave between an obstruction and a radar. A correlation is found between a matched filter 80 and a correlative operation part 100 to find a distance up to the obstruction. A Doppler component is extracted in a Doppler measurement part 60 to find a relative speed. An obstruction probability by other devices is lowered. The distance and speed are speedily measured simultaneously. Signal processing gain can be made high and sensitivity can be ensured with small transmission power.

Title: Manufacture of multilayer wiring board
Inventor: SANKI SADAHIKO
IPC: H05K3/42
Filed: 1991-03-15
Abstract: PURPOSE:To enable a multilayer wiring board where a metal film is formed on the inner wall of a through-hole or a viahole through an evaporation method to be manufactured. CONSTITUTION:An argon atmosphere is produced inside the through-hole or a viahole of a wiring board where a metal film is evaporated, whereby evaporated atoms are made to easily enter the through-hole or the viahole. In result, an evaporation film is formed on all the inner face of the through-hole or the viahole. (1): a film can be evaporated on all the inner surface of a through-hole. (2): usually, a wiring layer is formed through an evaporation method, but a metal film is formed on the inner wall of a through-hole or a viahole through an electroless plating method, because it can not be formed through an evaporation method, so that two processes are required and consequently the board concerned is increased in processing cost. By this setup, the formation of a wiring layer and the formation of metal film on the inner wall of a through-hole or a viahole are carried out at the same time, so that the board of this design can be enhanced in productivity and lessened in processing cost.

IPC: G02B6/42
Filed: 1983-03-28
Abstract: PURPOSE:To obtain an isolation function effective to the light reflected not only from the incident end but also the other end of an optical fiber by providing and connecting an optical fiber for maintaining the plane of polarization to the top end on the laser side of an optical fiber for transmission. CONSTITUTION:An optical fiber 7 for maintaining the plane of polarization having (2m+1)L/4 length on the light source side of an optical fiber 5 for transmission. The linearly polarized light emitted from a semiconductor laser 1 passes through a polarizing prism 3 and is coupled to the end face of the fiber 7 but the incident end face 7c of the fiber 7 is inclined relative with the optical axis of the fiber 7 and therefore the light reflected from said face is not coupled again to the laser 1. The light incident to the fiber 7 is reflected from the other end face 7c and the incident face 5c of the fiber 5 as well and when the light returns to the incident face of the fiber 7, the perpendicular plane of polarization is converted to linearly polarized light which is perpendicular to the polarizing direction of the laser 1. Such light is taken out at the other by the prism 3 and is not coupled again to the laser 1, by which an isolation function is maintained.

Title: Production of electrophotographic photoreceptor
Inventor: KOBAYASHI HIROTAKA
IPC: G03G5/00
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To produce an electrophotographic photoreceptor uniform in photoreceptor characteristics by adjusting the luminous intensity of light on the surface of a photosensitive layer at cooling process to be in a specific range. SOLUTION: In a method for producing the electrophotographic photoreceptor, which is comprised of coating a photosensitive layer directly or through an undercoat layer on an electrically conductive base body, then heating to dry and cooling, the luminous intensity of light on the surface of the photosensitive layer at the cooling process is controlled to >10 and <=100 lx. In this case, the photosensitive layer is effectively formed as the laminated layer type obtained by laminating a charge generating layer and a charge transporting layer or the single layer type. For example, the electrophotographic photoreceptor is composed of the electrically conductive base body 1, the undercoat layer 2, the charge generating layer 3, the charge transporting layer 4, the surface protective layer 5 and the photosensitive layer 6.  An electron acceptor is added, as occasion demands, into the photosensitive layer 6 of the photoreceptor of the laminated type or the single layer type, in order to improve sensitivity, lower residual potential or reduce changes in characteristics at the time of repeated use. As the electron acceptor, a compound having large electron affinity, such as succinic anhydride, maleic anhydride or the like, is cited.

Abstract: PURPOSE:To measure the minimum identifiable temperature difference(MRTD) efficiently by notifying the possibility of the identification between a target and a background based on the automatic change of the temperature difference which is set based on the setting of temperature parameters. CONSTITUTION:An operator inputs a temperature controlling parameter 10 through a keyboard 9b. After the completion of the input, an initial value of target temperature command is set at a target temperature command 5 and an initial value of a background temperature command is set at a background temperature command 6 for a collimator control device 2. A CPU 23 is set in an interruptible state. After the wait of a specified time, a temperature-difference changing rate corresponding to the range of applicable temperature difference is selected based on the present temperature differences of the commands 5 and 6. The command 6 keeps the initial value. As the command 5, the value obtained by adding the temperature-difference changing rate to the present value is set. When the infrared-image observer depresses a switch 12 during the repeating processing, a switch-state signal 13 generates the interruption for the CPU 23 with an interrupting circuit 18. Thus, an MRTD computing means 14 inputs a target temperature 7 and a background temperature 8, computes the MRTD 15 with a specified numerical expression and outputs 21 the result to a printer 16a.
